She is back in style: this week, Britney Spears broke another record in the recording industry. In just seven days, the single "Hold It Against Me", released on iTunes, hit number one on the Billboard chart in the United States and 19 other countries. A new milestone for a female artist, beating the likes of Madonna and Lady Gaga.

* The thing is that Britney achieved such a feat with almost no promotion. She didn’t appear in any big TV show nor released any bombshell videos. After a burst in sales of the Apple store, Britney thanked on Twitter: "Seriously, I have the best fans ever. I love you all so much!! Everything I do is for you!"

* And it’s only natural that such a feat should attract a lot of attention. Britney is this week’s hot topic in the U.S. media. In Jimmy Kimmel’s talk show, they picked on the girl, making up new creative names for her songs. All publicity is good publicity…
